Insert for carrier board of test handler

Abstract

An insert for a carrier board of a test handler is disclosed. In a first aspect, the latch block applying to the insert is detachably coupled to the insert body. The latch block can be reused, and thus this reduces wastage of resources and eliminates the insert replacement fee. In a second aspect, the insert pocket having hooks is detachably coupled to the insert body. The insert body can be reused. The latch unit is installed to the insert pocket, so that the damaged latch unit can be easily replaced. The insert forms a plurality of holes in the bottom of the loading part thereof, to expose the leads of the semiconductor devices through the holes downwardly. Thus, the insert can load semiconductor devices regardless of the dimensions of the semiconductor devices.

What is claimed is: 
     
       1. An insert for a test handler, the insert comprising:
 an insert body having a placing compartment in which a semiconductor device is placed; and 
 a pair of latch blocks for holding the semiconductor device placed in the placing compartment, wherein the pair of latch blocks are detachably coupled to the insert body, each latch block comprising a latch and parts for operating the latch, 
 wherein the insert body includes two block receiving openings formed on opposite ends of the placing compartment and receiving the pair of latch blocks therein, a catching jaw and a protrusion for preventing the pair of latch blocks from being removed in an upward direction, and a downward direction, 
 wherein the insert body forms the catching jaw on the inner wall of a block receiving opening, 
 wherein the pair of latch blocks are each received in the block receiving openings of the placing compartment, separately and respectively, 
 wherein the pair of latch blocks are configured in such a way that each latch block includes the latch for holding the semiconductor device placed in the placing compartment and the parts for operating the latch, where the latch and the parts for operating the latch are integrally assembled in the latch block, 
 wherein the latch blocks comprise predetermined physical dimensions according to physical dimensions of a plurality of insert bodies in each of which different dimensional semiconductor devices are placed, and wherein the predetermined physical dimensions concurrently avoid interference with each of the plurality of insert bodies, so that the pair of latch blocks can be reused with the different dimensional semiconductor devices and the plurality of insert bodies, and 
 wherein the pair of latch blocks form a catching boss that is elastically and movably caught to the catching jaws to prevent the pair of latch blocks from separating when the latch block is received in the block receiving opening. 
 
     
     
       2. The insert according to  claim 1 , wherein the pair of latch blocks are detachably coupled to the insert body through a coupling member.
